possible,though is seems to lack a serrated edge that most shark teeth seem to have,also that sterch ob beech would have been land dering the last ice age so there would have been no sharks there then,but then I also have no ldea how old is woud be either.

Quagga is quite correct this is a sharks tooth. They are commonly found at Felixstow beach. Don'tworry about what was happenning 13000 years ago during the last ice age I believe this is from the Red Crag which were laid down 5 million years ago.

There are many species of shark that lack serrations, and as I pointed out your tooth is also rather worn. London Clay exposes on the shores around Felixstowe. This was formed under a shallow warm sea. Shark teeth are often found in London Clay. Walton-on-the-Naze is particularly good for shark teeth.

It does look very much like the teeth in the wikipedia link, I'm convinced now that's what it is, from a shark that most likley ate fish and squid (like a sand tiger maybe), a tooth for pearcing and holding rather than cutting and sawing. What really amazed me was that I spotted it in the first place.

Thanks for your help, it's been very intresting, any more thoughts on this would also be intresting.
